SPEGEFICATION forming part of Letters Patent No. 682,509, dated September 10, 1901.

Application filed J'uly 25, 1900. Serial No. 24,813. (No model!) To @ZZ whom it may concern:

Be it known that LNVILLIAM O. VANOE, a citizen of the United States, residing at New Albany, in the county of Floyd and State of Indiana, have invented a new and useful Oarbureter, of which the following is a specification.

This invention relates to a novel carbureter designed for the generation of a gas from a liquid hydrocarbon for lighting or heating purposes, the object in view being to provide for the volatilization of theliquid hydrocarbon by a burner tapped into the oil-main and for the formation of a combustible gas within a commingling and distributing head located adjacent to the vaporizing-burner and designed to supply the gas thus formed to any desired number of burners located beyond the distributing-point. To the production of such a device the invention consists in leading an oil-supply pipe from a suitable reser- Voir to a distributing-head and in vaporizing the oil immediately before it reaches the head by means of a burner supplied with oil from the oil-pipe and directing its flame against a horizontal portion thereof to cause the volatilization of the oil substantially injected in the form of a vapor into the commingling-chamber of the distributing-head, the injection of the vapor eecting its commingling with air to form a gas designed to be supplied from the head to a gas-main for conveyance to the point or points of use.

The specific construction and arrangement of the apparatus will be more fully described hereinafter and will be clearly understood in connection with the accompanying drawings.

In said drawings, Figure 1 isa sectional view of my apparatus complete, certain of the parts being shown in elevation; and Fig. 2 is a sectional view through the distributinghead on the line 2 2 of Fig. 1.

Referring to the numerals of reference employed to designate corresponding parts in both views, 1 indicates a supply tank or reservoir for a liquid hydrocarbonas, for instance, gasolene-designed to be fed to a depending oil-pipe 2, provided at its lower end with a horizontal extension 3. The feed of the hydrocarbon may be maintained by gravity or by a pump or similar apparatus in the manner well understood in the art and in accordance with the quantity of gas required to be generated by the apparatus. At a suitable point in the horizontal branch 3 is interposed a three-way fitting 4, into which is screwed the lower end of the burner-supply pipe 5, screwed at its upper end to the supply-port 6 of a vaporizing-burner 7. The burner 7 is of ordinary form and comprises the burner-cap 8, resting upon the burnerplate 9, having a central open-ended flue 10 and formed on its under side with oil-passages 11, through which oi-l is supplied from the port 6 to a depending angular pipe 12, controlled by a valve 13 and leading to a needle-valve chamber 14, located directly' under the burner-flue 10. The oil is designed to be vaporized while passing through the passages 1l by the heating of the plate 9 in close proximity to the iiame of the burner and issues in the form of a vapor from a jet-orifice 15 in the upper end of the valve-casing 14. The injection of the hydrocarbon vapor through this opening into the flue 1() for consumption by the burner is controlled by a needle-valve 16, and, as usual, a drip-pan 17 is mounted on the casing 14 for the reception of oil for use in starting the generation of the vapor when the apparatus is first brought into use.`

Immediately above the port 6 the burnerplate 9 is pierced by the lower end of a continuation of the oil-pipe 5, having a horizontal portion 18 located immediately above the burner 7 and terminating in a vertical end 19, which supports what I will term the vaporizing or distributing head 20. This head, which, as premised, is designed for the formation of the 'gas to be supplied to the lighting and heating devices,comprisesasubstantially circular plate 21, having an enlargement 22, formed with a recurved port 23, into one end of which is screwed the upper extremity of the pipe 19, and at its center the plate is provided with an open-ended iiue or cornmingling-chamher 24, communicating with a gas-main 25, serving as a conduit through which the gas is distributed from the head 20 to the point or points of usethat is to say, to one or more burners designed for lighting or heating purposes,or both. From the other end of the port 23-that is to say, from the end opposite the pipe 19-depends a short angular vapor-pipe 2G, terminating in a con- IOO trolling-valve casing 27, containing a controlling-valve 2S and communicating with a vertically disposed needle valve casing 29, having its jet-orifice 30 located directly under the flue or commingling-chamber 24 and controlled by a needle-valve 3l. The distributing-head 2O is located in close proximity to the Vaporizing-burner '7, but is located to one side thereof in a slightly higher plane. Il

have therefore provided for the protection of the head from the heat of the burner by securing a metal shield or hood 32 upon the,

plate '2l and extending downwardly from said plate to a point a sufcient distance below the pipe 26 to preclude the possibility of the ignition of the vapor injected from the needle-Valve casing y.29 to lthe interior of the commingling-chamber 24. This shield or hood 32 has a substantially semicircular cross-sectional contour, so as to leave the` head freely exposed to the air :from the side opposite the vaporizing-burner,and while its mea-ns of attachment to the ,plate 42l may be`` varied its :up-per `end is preferably bent outwardly to form horizontal flanges secured to the underside of the plate.

In use the operation-of the apparatus is as follows: -Oil fed to the oil-pipe 2 from the reservoir l under the impulse-of gravity or by 'the employment of any desired form of positive vfeed passes through the burner.

pipe 5 to the head 20, 4a Ismall percentage of the Yflow being rdiverted to the vaporizing burner -7 for the support of sufficient -coml the distributing-head and thence through the Assuming the needle-valve301to bein an open bustion to vaporize :the main ilow of yoil yas, it passes through the horizontal portion 180iy they oil-pipe on its way [to :the head. The.

position, ajetof Vapor Wil-l be'ejected from the orifice 30 into the `vaporizing-chamber 24, 1

drawing with it a sulicient quantity of air to forma highly-combustible gas when-commingled with and carbu-reted by the Vapor. 3

The .gast-bus formed is conveyed through the gas-main 25, Where it is supplied Ito any de-E sired number land character of burners.

From the foregoing it will be seen that Il have produced a simple and yefficient carburetingg .apparatus for ,producing la combustible gas Afrom a liquid hydrocarbon, and it is obvious that it may be 'used in connection with various forms of .heating and lighting apparatus and with :heating or lighting sysl tems,-orboth; but while the present Vembodireservoir, 4an voil-pipe leading therefrom and means for heating said Apipe to Vaporize the oil, of a commingling and distributing head comprisinga plate formed with an open-ended commingling-chamber and with a port located t-o one side of the commingling-chamber, one end of said port boing in communi'- cation with the oil-pipe, a valve-casing suspended from the plate and in communication with the opposite end of the port in said plate and having a jet-orifice arranged to inject vapor into the lower open end of the commingling-chamber of the head, and a valve Within the valve-casing.
